[Elecraft] KPA-1500 Power Supply Cable Size

[john at kk9a.com]

It is good it will accept a larger conductor, especially for someone wanting to move their KPA1500 power supply further from the amp portion.  I had a tough time installing 8 awg to the PowerPole 45 amp K3S connector which is designed for 10 awg max.

I purchased 75 amp Anderson Powerpole connectors and #6 flex speaker cable from Debco Electronics for my extension cable. #6 fit easily. I suspect even #4 would have fit, but I see no reason to get that large.
